Table 5. Surgery duration, time to extubation, length of stay, and PONV.
*Significantly different from saline group.
**Significantly different from BPVC group.
***Significantly different from BPVC+BPRN group.
Values are mean±SD or number (percentage of patients). P-value <0.05 is considered statistically significant. Significant differences due to the statistical power considerations only for all (male+female) and males are shown.
BPVC: bupivacaine; BPRN: buprenorphine; MG: magnesium; PONV: post-operative nausea and/or vomiting
